Square: Bitcoin payments are open to eligible merchants in the United States

Square plans to complete a phased expansion of Bitcoin payment arrangements, with Lightning Network payments being opened to eligible sellers in its U.S. merchant network. Consumers can pay with Bitcoin, while merchants will default to receiving dollars but can choose to retain Bitcoin.

Square will waive Bitcoin payment processing fees until the end of 2026, after which it plans to charge a uniform fee of 1%. Square's broader merchant network covers over 4 million merchants, but eligibility restrictions still exist, and actual adoption has not been independently quantified.
